I sent a sample to the video4linux mailing list, but no result so far.

I've spend a day trying to revive v4l2src, and it basically comes down to
copying *lots* of code from v4lsrc. Much of the code is identical. (I guess
v4l2 src was copied from v4lsrc, but v4l2src was left to rot). Instead of
doing all this work and ending up with a v4l2src that is going to break at
the next API change, wouldn't it be a good idea to combine the two? Perhaps
still allowing selection by means of a property or so, or otherwise just at
Why do people still use v4l1 anyway, for old kernels? Or does it offer
something v4l2 doesn't have?
